The UK Border Agency (UKBA) was the border control agency of the Government of the United Kingdom and part of the Home Office that was superseded by UK Visas and Immigration in April 2013. It was formed as an executive agency on 1 April 2008 by a merger of the Border and Immigration Agency (BIA), UKvisas and the Detection functions of HM Revenue and Customs. The decision to create a single border control organisation was taken following a Cabinet Office report.
